STEADYING DEVICE FOR t' Application led .Tune 4,

To allwlwmz'tmay concern:y 1

Be it known that I, ALBERT BARBEZIEUX', a citizen of the Republic of France, and residin at Paris', Seine Department, No. 3b rue oyswox,l in the Republic of France, engineer, have invented certain new and useful Improvements in Steadymg Devices for Vehicles', of which the following is a specification.

This invention relates to a device affording av steady running for vehicles when making turns upon the road and for preventing them from tipping. In fact, when the vehicle is travelling around a curve in the road, the body of the vehicle is subject to tipping on its springs by reason of the centrii'ugal force occasioned by the speed, whereby the centre of gravity of the vehlcle is displaced towards the outer side of the curve and an unsteady running of the vehl- The device according to my invention has for its eiect to ease the outer spring whenA going aroundcurves and on the contrary to` load' the inner spring, thereby maintaining the vehicle body in the horizontal position or even inclined towards the outside of the curve. To this end it may be provided, for each wheel, with one or more cylinders each containing two pistons whose rods are re-` spectively connected with the vehicle frame and the axle, as well as a Huid-control de. vice actuated by the steering parts in such manner as to supply compressed air or like iuid under pressure either to one side of the vehicle and between the said pistons or on the outer side of each piston, or in the contrary sense, to the other side of the vehicle in such manner as to produce a like The accompanying drawings show by way of example a form of construction of the apparatus according to this invention.

Fig. 1 is a diagrammatic view of the entire installation.

Fig. 2 shows one of the steadying cylinders in perspective, with certain parts 1n section.

Fig` 3 is a front view of the fluid-control device in the neutral position.

Fig 4 is a cross-section of the same. Figs. 5 and 6 showthe said Huid-control device in front view` in the positions for passin around curves.

number for performing the re uisite work wlthout being cumbersome. ach of the said cylinders is provided with two pistons 4, 5, the piston rods whereof are respectively connecte bythe socket joints 8 and 9 with Compressed a1r 1s introduced between the pistons 4 and 5 through the orifice 10, a second -orifice 11 being vused on the contrary for admitting air at the same time to the opposite sides oi the said pistons. By suitably regulating the distributlon of compressed air, a pressure may thus be exerted between the axle and the vehicle frame, or on the contrary a traction tending to draw them together.

This adjustment'is automaticall obtained by the -device shown in Iig. 5. is device comprises a main cylinder 12 provided with three necks 13, 14 and 15. The neck 15 is connected with a compressed air reservoir 16 supplied by any suitable compressor, this latter being driven automatically byl the vehicle motor, for instance and is provided with a safety device for uncoupling the said compressor when required and subse uently coupling the same. The neck 14 ig. 1 is connected through the ducts 16, 17 with the space between the pistons of the cylinders situated on the right-hand side of the vehicle, and through the ducts 18 and 19 with the spaces outside the pistons of the cylinders disposed on the left-handA side. In like manner, the neck -15 is connected through the ducts 20 and 21 with the spaces between pistons of the left-hand set, and through the ducts 22 and 23 with the spaces outside the pistons of the right-hand set.

In the diagrammatic view, the steadying device-is supposed to contain two cylinders at the rear of the Vehicle and disposedat the sides, and a single cylinder at the front of thevehicle, the fluid passages being suitably branched to this eiiect, but any suitable number Vof cylinders may be used. Within the main body 12 is disposed the revoluble drum 24 having formed therein the ports 25, 26, 27 and 28. These latter are so disposed that in the position shown in Fig. 5, the compressed air passes through Fi 6, the air passes through. the ports 23 an 27 to the neck 15 for the supply of the connected byv a link 30 tothe steering vc linders through 20, 21, 22, 23, whereby the right-handpistons are brought together and the left-hand pistons separated, this belng' the ition for a right-hand turn. T e drum. 24 is controlled by an arm 2g 31 of the vehicle, and in this manner the supply of compressed air is automatically controlled in the proper manner by the solel action of steerin the wheels., The main b ody 12 is closed ya cap 32 having there-I in an aperture serving to guide l"thestud 34 secured to the drum 24 and fitted 1nto the arm29. On the other hand, when chang# in hsgid turn of the vehicle, it is `required toover ,from fa left-hand turn to a right discharge the compressed air containedin the necks 14 and `15 are connected together by the passage 35, the' duct 36' being opposlte a solid portion of the said cap, and this po- I,

sition affords an equilibrium of pressure.

In this case the apparatus will act as a shock- 4said drum will take for instance t e posi.

absorber' with ycompensating effect for considerable movements of the vehicle to' either side. Should the steering be chan d, the

tion shown in Fig.- 5; whereby the neck v15 will'be connected with the outer air through 35, 36, 38 and 39. On the contrary, as 'shown in- Fig. 6, the neck 14.now serves for the discharge. The compressed air thus evacuated may be used inv an acoustic horn which is suspension means connected with the steer-l connected with the orifice 39, in such manner that at each turn of the road the ho willbe automatically actuated. It "s understood that a suitable device -will be provided whereby the driver may prevent this latter operation, and he may even be enabled to prevent the action of the steadying device itself, for instance when wit in the city limits.

Aside from the safety which is' afforded by the device Vaccording to this invention, it should be remarked that the comfort of the vehicle will be much increased from the absence of tip-ping when going around curves.
